Question

find the length of the side of cube whose total surface area measure 150
cm square

Answer 1

surface area =6×a×a
=150

a^2=150/6=25
a=5 cm



so

the length of the side of cube whose total surface area measure 150
cm square is 5 cm

Answer 2

let a be the side of the cube .

Given,

total surface area of cube = 150cm^2



6a^2 = 150 => a^2 = 25


a = √25 = 5cm


each side of cube = 5cm


Answer: side = 5cm
